@Akari MG Ghost and Initial D have nothing in common really- I haven't actually watched / read it because one of the things that makes D -so- special is the extensive consulting work of Keiichi Tsuchiya (a legendary Japanese racing driver himself), and MF Ghost forewent that consulting and from what I've heard, really suffers from it.
I might still check it out just to see, but the disappointment from the car / Initial D community was loud enough that I haven't had much interest.
Wangan Midnight though is another one that's really worth checking out.
